RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Created attachment 1153785 [details]
'pcs cluster report' output

Description of problem:

Heartbeat:LVM resource agent activates type1 partial vg even though it has
partial_activation=false set.


Version-Release number of selected component (if applicable):
resource-agents-3.9.5-34.el6.x86_64

How reproducible: always

Steps to Reproduce:
. create vg consisted of several shared pvs
. create lvm raid on this vg. I used the following command:
    lvcreate -ay --name raidlv --type raid1 --extents 100%VG \
    --nosync --mirrors 1 \
    raidvg
. create cluster ready to use halvm
. create lvm resource with partial_activation=false atop of raidvg
. start it
. fail one of the disks on the node running the resource:
  # echo offline > /sys/block/sda/device/state
. disable the resource
. check that vg is seen as partial on all nodes and the 'offline'd disk is
    recognized as missing
. enable the resource

Actual results: lvm resource starts 

Expected results: lvm resource refuse to start on any of the nodes

Comment 3 Alasdair Kergon 2016-05-06 17:53:24 UTC 
(Obviously "(null)" should not be appearing in the lvm message that reports a detected misconfiguration.)
Comment 4 michal novacek 2016-05-10 12:49:30 UTC 
(In reply to Alasdair Kergon from comment #1)
> And which lvm2 package version?

$ rpm -q lvm2
lvm2-2.02.143-7.el6.x86_64
Comment 5 michal novacek 2016-11-07 13:49:12 UTC 
The same issue occurs in RHEL 7.3: lvm resource agent does activate partial vg with partial_activation set to false.

Comment 10 Oyvind Albrigtsen 2017-01-26 09:58:07 UTC 
stderr (not stdout).
Comment 13 Oyvind Albrigtsen 2017-01-27 14:17:47 UTC 
Updated patch:
https://github.com/ClusterLabs/resource-agents/pull/921
Comment 15 michal novacek 2017-01-27 15:09:28 UTC 
I have verified that LVM resource agent will not activate lvm volumes marked
partial when partial_activation=false with resource-agents-3.9.5-46

---

Common setup:

* have configured running cluster (1)
* have raid vg configured atop of several pvs (2)
* create and start LVM resource for this vg
